Dear Alice，

As a teenager，I met the same problem as you. But now I can get along better with my mother. Here are some ideas for you。

Your mother talks much，because she cares about you. Maybe its not a good way，but it shows your mothers love. So I think you should listen to her. If your opinions are different from your mothers，you can communicate with her，and tell her what you are thinking about。

If your mother doesnt take your advice，just keep silent and give her a smile。

I hope what I say here can help you a lot。

环卫工人是我们城市的舒适环境的创造者，他们让整个城市变得干净和美丽。他们应该得到我们的尊敬。下面，小编整理了几篇关于环卫工人的英语作文，以供大家参考。

关于环卫工人的英文作文一

Each time I feel very emotional after reading the news about bad or unfair treatment towards city hygiene workers. On one hand, they have to suffer the poor working environment; on the other hand, they do not earn the respect from the society or public. It is a very sad fact in China, which is a wake-up call for us to face the situation in good manner. In my opinion, the education background differences outweigh other factors. People who are not well educated do not see the hardwork and uneasy life of those city beauty workers. All they care is their own feelings and interest. Moreover, if we do not appreciate or cherish others devotion to the city, the city as a mirror will reflect its bad side towards ourselves. Therefore, the public need to learn to respect and behave properly such as not throw about the garbage. In addition, the government should also make its efforts to improve the treatment of those sanitation workers as well as set up a good example in the public.

关于环卫工人的英文作文二

To be a sanitation worker can never be considered as a decent job in peoples eyes, especially in China. A story of Sanmao, a Taiwanese author, described that she wanted to be a garbabge collector and she wrote this in her homework in her elementary school but teasing and objection came from her teacher and classmates. There is nothing wrong about a childish girls idea, and she thought that job could provide the most freedom. But this reflect the obvious discrimination. However, there is a dustman in my department. Everyone says hello, chats, jokes, and respects him as respect any other professors and students because people dont see differences between jobs.

关于环卫工人的英文作文四

In cold winter, people are warming up near the fireplace at home, while sanitation workers are cleaning the broken branches and falling leaves. Usually sanitation workers have always been very hard, plus cruel and merciless wind and snow will be cut off branches and leaves on the roadside, the road, the sidewalk ... everywhere, sanitation can be miserable. They took the knife to cut off the branches, took the shovel to shovel branches and leaves, and take the broom sweeping, tired in the cold weather sweating profusely, the cold wind did not feel cold, they forget the tiredness and cold. In such a cold weather, sanitation workers have cleaned up our Fuzhou streets and won peoples respect. We should learn from sanitation workers and learn from their hard-working and optimistic spirit. In extraordinary positions, to make extraordinary things, although their own dirty, but Fuzhou city has become more beautiful. When people see such a clean street, they think of sanitation workers as the hardest people and the loveliest people.

Travel security, is not only related to his own life and safety, also respect others life to reflect, it is to build the harmonious societys important factors. Through the flow traffic, "loving the life, safe travel" eight words in my mind appears more prominent. Mention travel security, it is hard to let a person think of traffic safety. In daily life, traffic safety always around us. As long as you travel with traffic safety, and hit the idea. An absent-minded, when walking when crossing the street when a fluke, drive a violation, is only a little oversight, all these will make a life is transient.

Fly xuan wheels will mercilessly devoured the pedestrians life.

Ever seen a story:

"national every 6 minutes will have one person died of a wheel under". This is not true.

Bitter facts once again give us was a wake-up call: "civilized journey, civilization walk". Modern traffic developed although has brought people endless facilities, but also increased a lot of security lapses. Someone once said traffic accident for "modern social traffic war", traffic accidents like an invisible killer, lurking in the road waiting for illegal illegal person appear. Therefore, people should learn to protect themselves, make a civilized journey, civilization walk habit.

"Human life only have once," "the most precious is life", the blood tragedy told we must abide by traffic regulations, accomplish truly "loving the life, safe travel".

Safe travel, builds the good traffic running environment for the harmonious societys construction unconscious, and building a harmonious society and to the construction of traffic safety hold up a blue sky. This is a win-win wisdom. As an ordinary pupil, abide by traffic regulations, maintain traffic order is we should have the social morality. "Civilization walk, to construct harmonious", this requires each citizen starts from oneself, from small start, let "peace avenue" more unimpeded!

Mr. Louis is my Chinese teacher. She was of medium height, slender, with two eyebrows on her lanky face, a pair of squinting eyes, and a pair of pink glasses on her high nose, about thirty years old. Her speech was vivid and vivid in class, her tone was cadenced and her emotions were real. People are kind and strict.

I remember that it was one of the things that happened early on, and I came to the school early in the morning and put my exercise books on the table, and I happily picked up the Chinese book and read aloud the text aloud.

After about a quarter of an hour or so, Mr. Louis walked into the classroom with a smile on his face, went up to the lectern, took out the red pen and handed the students the homework. After more than ten books, I found that the teachers face gradually changed from sunny to cloudy, and some of my classmates workbooks were taken to the stage. When it was my turn, my heart was both happy and afraid. I was glad that the teacher could see the homework I had finished. The fear is that the teacher will also take away my exercise book. Not sure enough, I saw the workbook lying on the table, trying to get it down, but it was impossible.

After class, the teacher overlooks his face and says to us, "if you want to have a workbook, please come to my office." Then he picked up the book and went away. I breathed a sigh of relief, but I was still not happy. I didnt know what was waiting for me: reprimand, criticism, praise... Oh, I dont think so.

After the second lesson, I and the students went to the teachers office and prepared to be taught. Who knows, the teacher changed the normal, kindly say: "last night go back why dont finish earnestly, ask you a few to correct the error in the workbook." Several of us took the exercise books nervously and fell on the teachers desk to correct them all. Then, let the teacher see again. Then the teacher smiled and said, "thats right. The people who read more should pay attention, the homework also cannot be careless!" We listened, and the mood was like a stone falling to the ground and running out of the office.

You say, how can such a teacher not let us like?

Dear Lisa,

Hows it going? My winter break is coming soon, and here are my plans: Im going to read five novels because I love reading. I realized that I have gained a lot of weight, so I also plan to exercise every day until I lose five kilograms. Moreover, I want to watch some good movies, too. After all, the vacation is for us to relax! Right? Haha. Do you have any plans for your winter break? Write back soon! I miss you tons!

Love,

Dear parents,

“You always say that I am naive. In your eyes, I am always the little girl who will never grow up”. This is my favorite song and also the sound from the bottom of my heart. You made me feel so lucky to be your child. But I find our hearts getting further apart as time goes by.

You strictly forbid me to do entertaining activities even if I finished my homework, such as watching TV or playing computer games. Based on this, I couldn’t get any grade less than A. It is said that genius only means hard-working all one’s life. But I think combining exertion is the best way for learning.

The most important thing to me was that I feel frustrated for having few friends to confide in due to your strict rules. I can’t have a play date, participate in a school play or even choose my own extracurricular activities. Who will accept such a boring and troublesome person? I am just an ordinary girl who can’t stand loneliness, so I always feel contradictory.

On the one hand, I’m grateful to have you in my life, to disappoint you was the least I would do. On the other hand, what you asked for me made me felt like a puppet rather than a real person. I appreciated your efforts to pull me away from a self-indulgent life, but your obsessively extravagant strictness has pushed me into an isolated and insensible one. I need a little freedom so that I will concentrate on something I really interested in.

Father and mother, these words were hid in my deep heart for a long time. I love you, and I believe if you change some harsh rules. I will have a wonderful life.

Best wishes.

Yours, daughter

One winter afternoon, I went to the balcony to wash my hands. Suddenly I saw a bird hiding in the corner of the balcony, trembling all over. I crept close to the bird and saw a broken wing on the birds wing. It was still bleeding. I see a bird fly near it, but dont fly to the corner close to the eyes, staring at me, afraid I hurt it, a faint voice.

I quickly called mom, mom said: “ Oh, this bird is so dirty, hurry away. &rdquo: I quickly said, "&ldquo, no, no, the bird is good for the birds. The little bird is hurt again. Its pathetic. His mother cant find it. Itll hurt.". &rdquo, mum nodded.

I put the bird in a pot, help it deal with the wound, then sprinkle some millet in a pot, put a glass of water.

A few days later, the bird got hurt and played with me, singing and singing as if to say, "&ldquo, boy, thank you."! ”

One day, when I went to see the bird again, I suddenly found the bird disappeared. I think the bird should be looking for mother and son!

I have a lot of friends, but my best friends are Alex and Liu Jingyan! They can help me when I am in trouble, and when I am sad, they can comfort me, and when I am happy, I will share happiness with them. And you?

Im sure youll be the same as me. Theyre two introverted little girls, just like me, because of that, Ive made good friends with the two of them. Not only for reasons, but also for other reasons, they will always be my best friends!

Recently we did a survey in our class in order to learn about students’

ideal jobs. Here’s a report about my group members’ ideas.

Mary wants to be a fashion designer because she likes beautiful clothes and

is good at drawing. Kate wants to be a gardener, she lives plants, and she wants

to make the cities better. Mike would like to be a writer. He’d like to share

his wonderful stories with others. Tom would like to be a cook. He’d like to

cook delicious food for others. I would like to be a policeman. I want to

protect the people safe.

Hopefully everyone can realize their dreams in the future.

Dear Editor,

I’m writing to tell you how us use computers in our daily lives.Most of us

use computers to search for more information about the interesting problems on

the textbooks, about Iraqi wars and about Oscar. Some of us use computers to do

some drawings, to make up interesting flashes. And some of us use them to play

games. If we are tired and want to take a short rest, playing games for a while

is OK. But it’s forbidden that we spend hours and hours on the games. There is

also someone using computers to talk with people in the Internet and even

falling in love with him or her. The Internet is not a real world and we can’t

tell lies from truths. So falling in love with somebody on the Internet is not

safe and is bad for our study. We should keep ourselves out of it.That’s all I

know.Good luck!

Yours truly,

Li Hua

一开门，就是一句“新年好，哈—匹—牛—叶（happy new year）！”哇，现在就连普通话都不怎么好的叔叔也有一口“流利”的英语，他说，他这是现买现学，这句话是刚从他儿子那学来的！

“哎，又是过年，过年最没有意思了，就知道在家里看看电视，也没什么好干的！哎……”我想现在的小孩子一定也有和我一样的想法吧。毕竟，现在的过年一点气氛都没有，以前，家家户户都会忙着挂红灯笼，贴“福”字，还有，就是赶着去买团圆八宝饭呢！年初一我们一大早就起床，然后约好了成群结队出去窜门，我们小孩子就在家里玩，然后一起吃团圆饭。可是现在就截然不同了，现在就连什么时候过年，我都会忘了，过年的前一天都在问什么时候过年呢！

早上，我硬是被爸爸妈妈给拖起来，只喝了一杯牛奶，就跑去客厅里来看电视准备打发时间，这时，爸爸妈妈对边看电视边打瞌睡的我说：不用看电视了，我们出去玩！” “有地方玩吗？” “有，你别忘了，现在这里住着的我们都认识，难道还不愁没人玩吗！”爸爸妈妈兴奋地说到。我们先到了最近的一户人家。 一开门， 就是一句“新年好， 哈—匹—牛—叶（happy new year）！”哇，现在就连普通话都不怎么好的叔叔也有一口“流利”的英语，他说，他这是现买现学，这句话是刚从他儿子那学来的！尽管有点不标准，不过在我这个大师的指导下，你别说还真有点长进！由于他们家还没有吃好饭，所以我们一家三口又继续出发了。后来，我们不仅参观他们的新房子，同时也道了新年贺词，啊多么愉快的事呀！挨家挨户都走过了，现在也该歇息歇息了，大人们在阳台上下象棋，瞧，他们还兴奋地说“出将”呢！有的在打麻将，一个个都想趁着这个新年有个好手气！， 有的客人还在看鱼，那些顽皮的鱼儿从假山的石缝里钻来钻去，让客人们忍不住那棍子去逗逗它们。而我们小孩子呢，哈，看电视的看电视，玩电脑的玩电脑，也都很快活！

Open the door， is a "good new year， ha — horse — Happy New Year！" Wow， even now， even Mandarin is not very good uncle also has a fluent English， he said， he is buying now， this sentence is just from his son learned。

"Well， its the new year， the new year is the most uninteresting， I know that watching TV at home， there is nothing to do！ Oh。。。 " I think the children now have the same idea as I do。 After all， now the new year a little atmosphere are not before， every family is busy hanging red lanterns， paste "Fu"， there is a hurry to buy Eight Delicacies Rice reunion！ At the beginning of the year we got up early in the morning and went out to the door in groups。 Our children were playing at home， and then we had a reunion dinner together。 But now its very different， and now even when the new year， I will forget， the day before the year of the year are asking when to celebrate the New Year！

In the morning， I was dragged up by my mom and dad。 I only drank a glass of milk and ran to the living room to watch TV and prepare to kill time。 At this time， mom and dad said to me while watching TV， dozing： no need to watch TV， lets go out to play。 "Do you have a place to play？" "Yes， you do not forget， now we live here all know， dont worry about no one to play！" Mom and dad said excitedly。 We went to the nearest family。 Open the door， is a "good new year， ha — horse — Happy New Year！" Wow， even now， even Mandarin is not very good uncle also has a fluent English， he said， he is buying now， this sentence is just from his son learned。 Although it is not standard， but under the guidance of my master， you cant say that you are a little better。 As their family did not have a good meal， the three of our family went on again。 Later， we not only visit their new house， also said the new year， how happy ah ah！ They have gone from door to door， and now its time to rest and rest。 People play chess on the balcony。 Look， they are also excited to say "go out"。 Some are playing mahjong， all want to take advantage of this new year with a good hand！ Some of the guests， watching the fish， those naughty fish from the rockery stones in the turn， let the guests can not help but stick to tease them。 And we children， ha， watching TV watching TV， playing computer and playing computer， are also very happy！

At night， we eat a meal， take advantage of the fine weather and scenery came to the balcony fireworks， "bang， bang， bang！" That blossoming flower blossomed on our head very beautifully！ Ah， this year is really good for this year！

recently, with the increasing busy life of our contemporaries, the loneness of the old ones has been existent as a widespread socail phenomena,which is really worth a plenty of social attention.

there are a couple of principal factors for this issue .most importantly ,it is because the young are so engaged with their work and study that it is difficult for them to find time visiting their old generations .furthermore, the unemployment of old people is another influential ground for their loneness since they may have too much free time and dont know what to do .

since the old generations have made great contribution to the society ,so,they should be respected ,accepted and cared .as for me ,they are at leats two ways to resolve this problem. first ,the old ones can raise pets like dogs or cats to have a accompany ,also, they can have a walk in the park,last, the young should care them and find time together with them as possible .

Dear Zhangxuan:

I am writing this letter to thank. First, I must thank the god, for letting

me meet with you, my best friend throughout my life. And then, thank you very

much for staying with me all the time.

From the time we know each other, every time when I meet with troubles, you

experiences with meAll these make me delighted. Although you are in Tianjin now,

Dear Mr. Seaton，

Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen the Tower or any of the other famous sights. If Id gone alone, I couldnt have seen nearly as much, because I wouldnt have known my way about.

The weather was splendid on that day, which I thought was rare. I still remember some people told me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. So I think I was lucky.

I think the river trip was the best thing of all. London really came alive for me as we saw it from the Thames during that wonderful journey down to Greenwich. It was all tremendously exciting - a day that I shall never forget.

Thank you for giving me such a great birthday treat.

Yours sincerely,

Linda Chen
